A multidisciplinary team of researchers combined DNA's physical capability to self-assemble, with the electrical conduction properties of gold tiny dots (nanodots). The work brings us closer to the development of novel types of nano-scale bioelectronic devices and molecular sensors.
DNA origami is a type of DNA self-assembled structure that can be programmed to form specific hooks to desired molecules. It is typically a flat structure of approximately 100 nm side, with over 200 positions on each face, where arbitrary DNA strands, proteins or polymers can bind and stabilize onto the DNA in predesigned paths and patterns.
